In light of the recent tragedy at Marjory Stoneman Douglas High School in Parkland FL, the issue of school safety has been brought into the limelight once more.

To increase security, US Congress and several state legislatures are investing in school surveillance systems with the goal of employing cameras to monitor common areas to enable real-time responses to potentially deadly situations as they arise.

According to John Medina in EdSurge, there are no easy answers to the question of whether technology does more harm than good to teenagers’ brains.

Medina’s article points to the lack of research on the many variables. As well as to conflicting reports from the research, including claims about the harmful effects of technology on attention spans and counterclaims about its ability to enhance attention spans.

If there is a clear takeaway here, it’s surely that we know even less than we thought we knew about how technology affects developing brains.

Recent reports show that 48 million Americans deal with some degree of hearing loss. This number is not a just age-related hearing loss – it affects 15 percent of school-age children too.

The Over the Counter Hearing Aid Act was initiated in order to allow people to buy cheaper hearing devices. This act also directs the US Food and Drug Administration to designate a new category of hearing aid that allows traditional headphone makers and technology companies to start developing devices to help those affected by loss of hearing.

The workforce is experiencing a disruption unlike anything seen since the Industrial Revolution. So claims Jeffrey Selingo in this long-form piece for The Atlantic. And it’s hard to disagree.

Selingo’s piece takes us through the multiple shifts education has undergone in the past century.

The expansion of high schools in 1910 to 1935 represented the first wave in a century-long effort to align education in the US to the changing needs of the economy.

The second wave in expanding education for a changing workforce occurred in the 1960s with the “college for all” movement between 1970 and 2016, during which enrollment in higher education more than doubled from 8.5 million to 20.5 million students.

Now economists, educators and workforce-development officials argue that the 3rd wave of the education revolution is here, and will be marked by continual training throughout an individual’s lifetime.
